E STATES PATENT HENRY MESINGEB AND FREDERICK MESINGER, OF NEW YORK, N. Y.

cosnron SADDLE.

Application filed September 23, 1921.

To all whom it may concern:

Be it known that we, HENRY MESINGER and FREDERICK MEsINcnR, both citizens of the United States, and residents of New York city, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Cushion Saddles, of which the following is a specification.

The present invention relates to improvements in cushion saddles and is intended for use particularly in conjunction wit-h bicycles and motorcycles and the invention has for an object to provide for resiliently supporting a saddle seat and further, avoiding that objectionable rebound which occurs consequent upon the compression of the cushioning springs incident to encountering inequalities in the roadway over which the vehicle is passing.

Another object of the invention is to provide a simple, compact and inexpensive structure in which the coil springs for cushioning the saddle are divided in effect and made to act in the dual function of resiliently supporting the seat and checking the rebounding movement thereof caused after a compression of the springs.

With the above and other objects in view, the invention consists in the improved form, construction and relative arrangement of the several parts as will be hereinafter more fully described, illustrated in the accompanying drawings and subsequently incorporated in the subjoined claims.

In the drawings wherein we have illus trated one practical and satisfactory embodiment of the invention and in which similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a view in side elevation of an improved resiliently supported saddle as constructed in accordance with the present invention,

Figure 2 is a horizontal sectional view thereof taken on the line 2-2 of Figure 1,

Figure 3 is a rear view of the device Figure 4 is a side view showing a slight modification,

figure 5 is a bottom plan view thereof, Figure 6 is a rear end view. I

Referringmore particularly to the drawing laiid-f rthe p esent to Figures 1, 2 and Serial No. 502,719.

3, 1 designates a saddle seat which in this instance is secured as by bolts 2 to an upper frame 3 preferably of heavy wire construction having its forward portion coiled into a number of convolutions 4 beneath and projecting slightly beyond the front tongue portion of the saddle 1 land constituting a resillent support for this portion of the seat. The ends of the wire frame work, after issuing from the convolutions 4 at their lower portions are brought rearwardly and are suitably rolled over to receive a transverse pin 5 to which the convergent ends of companion bars 6 and 7 constituting a lower frame are pivotally secured.

The bars 6 and 7 lie in a general diagonal direction and have openings 8 made therethrough to receive a bolt or other fastening by which the bars are clamped firmly upon the frame work or adjustable post of a bicyole, motorcycle, or the like. At their rear ends the bars 6 and 7 diverge as most clearly seen in Figure 2 and project down at an angle as illustrated in Figure 1. At this point a brace or bridge piece 9 is connected between the bars for the purpose of keeping them spaced apart and imparting strength to -the structure. For the purpose of connecting the rear ends of the bars 7 and the ends of the brace 9 to the respective springs, I preferably employ the rings 12 and 13. Each of these rings is provided with an internal spiral groove and may be threaded downwardly upon the lower cylindrical portions of the springs 14 and 15 to any desired position in spaced relation to the lower ends of said springs. The end portions of these rings overlap at the inner sides of the springs and are provided with coinciding openings to receive the bolts 10 and 11 respectively. These bolts extend between adjacent convolutions of the respective springs and have heads which are of sufficient diameter to extend upon the inner sidesof the two adjacent turns or convolutions of the springs. Suitable nuts are threaded upon the other ends of said bolts to tightly clamp or rigidly secure the ends of the bars 7 and of the brace 9 to the rings 12 and 13. Rods 16 and 17 extend axially through the respec tive springs. These rods 16 and 17 are in one piece with the rockshaft 18 which has a pivotal movement in straps or bearings 19 and 20 held by the bolts 2 to the rear undert e o th saddle seat 1. The rods 16 and 17 are threaded at their lower ends and receive nuts 21 engaging above and below the lower terminals of the springs. Thethreads of the rods are preferably continued over some length to secure an adjustment of the springs as to compression.

It will be noted particularly from Figures 1 and 3 that each cushioning spring is composed of a number of turns or convolutions wound concentrically about its respective-rod, the lower turns being uniform and encompassing"substantially a cylindrical: space, while the upper portion of each spring is made of turns or helices which progressively decrease in diameter. and form a frustum of a cone, the terminal upper helix engaging freely beneath the end of the rockshaft 18.

The action of the device is as follows:

When encountering ruts or other inequalities in' the roadway or surface over which for instance a bicycle is traveling, the shock received upon the Wheel is transmitted through the frame work and directly thereby to the bars 6 and 7. There is consequently anupward thrust which developsby causing the harsh and 7 to execute a swingingmovement about the pin center '5 and re sulting in carryingthe rings 12 and 13 upwardly to cause a compression of the pertions" ofthe spring 1 1 and 15 extending thereabove'and likewise, an extension of the portionsof such springs lying beneath these rings. The effect is to transmit the shocks and the jars to the seat saddle 1 only through the upper portions of thesprings and consequently, to absorb the force of these shocks and jars. As soon as the force of the sho cks and jars is spent, the upper portions of the springs above the rings 12 and 13 will tend to expand due to the elasticity inherent in the metal and this action will be assisted by the tendency of the lower portions of the springs beneath the rings to contract downwardly inasmuch as the latter portionsof thesprin-gs have been distended out of their normal position. Moreover, the lower por tions of these springs will form resilient and yielding abutments to cushion the down Ward movement of the rings 12 and 13 and to further absorb or cushion any shock that is apt to occur in the saddle seat 1 due to the rebound or return of the springs to their normal positions. In other words, the upper and lower portions of the springs when they are divided in the manner described by the rings 12 and 13 exert a mutually compeneating effect, the one upon the other, and together contribute to cushion the seat 1.

By the provision of the rings 12 and 13 and the means for rigidly fixing these rings upon the respective springs and to theends of the bars 7, the compression and extension of the upper and lower portions-of the springs'ifithe vertical movement of the bar 7 will be equally distributed circumferentially around the springs. Thusundue pressure at one side of the springs tending to exert'a bending or distortin strain upon the spring, coils or on the roc s. 16 and 17, is obviated and a better resilient" cushioning effect is obtained.

Referring more particularly to Figures 4, 5 and 6, an arrangement generally similar to that previously described is herein illus trated with the exception that the-rin 's 12 and 13 are dispensed with and: the heads 22 and 28' of the bolts 10' and 11 madeto ex.- tend within adjacent turns of the springs 14: and 15. The shanks of: these bolts are engaged between adjacent convolutions of the springs and transmit the stresses and strains therethrough in the same manner as the rings 12 and 13 except that the rings are continuous around the convolutionsrand they exert a more uniform distendilng and compression influence upon the springs; In this instance the bars G and 7 are alsodispen-sod with and heavy metallicwire rodszQ and 25 substituted therefor having downwardly curved intermediate parts. as shown in Figuret to reeeiveth'e seat postxor other rigid part of the=vehicl e frame.

While we have herein shown and; described the preferred construction and arrangement of the several elements, it will nevertheless be understood thatthe device is. susceptible of considerable modification in the form, proportion and relative arrangement ofv the several parts and we accordingly reserve the privilege of adopting allsuch lerritimate changes as may be fairly embodied Within the spirit and scope of the invention as claimed. a
